LI200X-L

Campbell

The LI200X Silicon Pyranometer is calibrated against an Eppley precision spectral pyranometer (PSP) to accurately measure sun-plus-sky radiation. The LI200X is used extensively in solar, agricultural, and meteorological applications. The LI200X should not be used under vegetation or artificial lights because it is calibrated for the daylight spectrum (400 to 1100 nm).
